growing a minimalist wardrobe: repair a wool sweater.

October 23, 2019

A few weeks ago I pulled out the storage bag where I keep the small amount of kids’ clothes that I’ve deemed special enough to keep for nostalgia sake, or that are otherwise waiting for the right-sized kid to fit into them. I wanted to see what few baby things I’d saved and to get a sense of what we might need with another little one on the way. To my delight I found a woolly fleece suit of Silas’s that I’d lent to my sister (and that we’d both forgotten she’d already returned to me), and a favorite wool sweater I’d received when Faye was a baby, that had since also been loved by Silas. Unfortunately, both beloved woolens had suffered a bit from time and our affection: I found a tear along a seam of the woolly suit and evidence that the sweater had been snacked on by unbeknownst-to-us resident bugs.

Felting to the rescue. In my thirty-five years I’d never embarked on a full felting repair of my own, but when over coffee with Rose, I bemoaned the fate of my favorite woolens, she assured me that I was up to the task. In typical Rose style, when she saw me next, she arrived with a pouch of materials I could borrow to make the fix.

The process was so easy and so satisfying. Not to mention, stress-relieving. It’s been such a great week for repeatedly stabbing an inanimate object with a sharp needle. Just one warning: Once you start, you’re not going to want to stop.

Materials needed and instructions below, plus a few woolly resources.

+ Wool item to be repaired (As a general rule, felting works best when working with 100-percent wool, though for smaller projects especially, don’t shy away from blends if that’s what you have. In my felting fervor, I had lots of luck felting over some goody bag masks that my kids were given, and they were decidedly not one-hundred percent wool.)

+ 100-percent wool roving

+ Felting needle (I borrowed a single needle from Rose to make these repairs and it was perfect. If you’re tackling a larger project or planning to felt a bunch, you might opt for a wooden needle felting tool that comes with a range of needles and the option to use multiple needles at the same time.)

+ Felting mat (I borrowed a felting mat similar to this bristle-style felting mat. You can also use a firm woolen mat as your felting surface (or, if you have one already destined for the landfill, a piece of dense styrofoam).

+ If your sweater is damaged due to moths or other pests (like this one), make sure you’re starting with a clean sweater to ensure there are no larvae present.

+ Place your felting mat underneath the small hole or area in need of repair.

+ Tear (don’t cut) a piece of wool roving in the color and size that you need and use your fingers to shape it into a puffy sphere. Place the roving on top of the hole and use your needle to puncture the roving into the wool you’re seeking to mend.

+ With every pierce of the needle, the roving will adhere itself to the wool sweater. Continue piercing the roving until it is well adhered and flat against the surface of the sweater.

+ Note: I used circles here in contrasting shades because I was repairing a baby sweater. If circles aren’t your style, feel free to choose matching roving or to work your roving into a different shape for more subtle (or creative!) repairs.

Incorporate the wool roving into the knit sweater by using a sharp felting needle.

Once felted, the repair should be flat and firmly adhered to the surface of the sweater.

    Moths aren’t the only insects that eat wool! Centipedes, cockroaches, silverfish, and house crickets often munch on wool clothing while looking for food residue – given that these items were used for young kids (who are not the neatest of eaters as a group) I would guess those other bugs are the culprit here.

    Oh – what a good idea. I recently got a thread up sweater that had a hole in it (they credited me the cost before I even received it)…this could be the perfect place to try it out.

  • Reply linda October 23, 2019 at 2:22 pm

    wow this is so cool! when you pierce the roving do you also pull the needle through the cloth and out the other end like a needle and thread or you pull it out the same way it enters the cloth?

    • Reply ERIN BOYLE October 23, 2019 at 3:47 pm

      Good question: you pierce and pull right back out, just kind of stabbing the same area over and over.

        Hi just wondered once the dry felting is done what happens to the added wool when the garments are hand/machine washed as usual? Does it pucker or loose shape?

          We’ve only hand-washed and haven’t noticed any puckering!

    This is so helpful. Thank you! As a knitter, this was new to me. I wonder if I leftover yard could be used in a similar way to the wool roving if it were frayed. If so, I’d have plenty of material for matching patches.

      I’m so glad you posted about this! I have two sweaters that need elbow patches. I have wanted to try Erica’s DIY method she wrote about on Honestly WTF, but for two years I have stalled out buying the supplies. (Too many different websites, not knowing how much roving to purchase, etc.) Thanks to you, I actually ordered the supplies today! Thank you so much.

    • Reply ERIN BOYLE October 24, 2019 at 9:21 am

      Hi Judith! I actually used a bit of frayed yarn to make some of the detail work on the felt masks I “improved” for the kids! The yarn I used was quite bulky and similar to roving in that it could be pulled apart, so I think that’s why I had success!

    This is just delightful! I love the polka dots you ended up with on that sweater. In my own quest to be a better steward of my clothing, I learned how to knit over a hole in a sweater I’d over-eagerly de-fuzzed. I had to watch a YouTube video about a thousand times to comprehend the steps, but I managed to mend that hole. I was pretty proud! You or other readers might also be interested in Reunion Yarn Company (, which offers workshops in sweater-unraveling so you can reuse yarn. And the last thing that comes to mind is the infinite variety of projects that can come out of felting wool sweaters by deliberately shrinking them: My mom made merino wool pants and sweaters from old adult sweaters for my two little ones, as well as a pair of running tights for me. Like you said, once you get on a roll, it’s hard to stop. Repurpose allll the wool!

    Oh I remember seeing a tutorial to felt heart shaped elbow patches onto a sweater – it was so cute! I love the ‘bubbles’ you have made for this little sweater as well. Precious! I think it is so special and fun to see pictures of siblings (and cousins!) in the same article of clothing – I was so lucky that my mother had saved quite a bit of our baby clothing and my daughter got to wear outfits that my sister and I had worn – and even a few things of my brothers!

    Wondering how you recommend washing the wool to be sure the larvae are all gone. Does the water need to be hot hot hot? Will hot water cause further damage? Thank you for this; I’ve pulled a sweater out that was munched 🙁 Grateful to have a fix now!

    • Reply ERIN BOYLE October 24, 2019 at 7:18 am

      We hand washed in cool water with soap just as always.

    • Reply Heather October 24, 2019 at 1:21 pm

      Freezing wool items for several days is supposed to kill moth larvae, so when I’m concerned about a sweater or other woolen item, I usually stash it in my freezer (in a sealed bag or container) for a week or so in addition to washing. I wouldn’t increase the washing temperature since the heat might shrink the fibers. I don’t know how many sweaters or scarves have taken a turn in my freezer over the years, sometimes just a precautionary measure because I really love them. 🙂

      • Reply Jenny October 25, 2019 at 3:20 am

        Also: DRY CLEANING. We had a moth infestation 2 years ago and did combination freezer and dry cleaning depending on the quality and material of the item.

  • Reply Abby October 24, 2019 at 11:02 am

    Brilliant. Weirdly, I have some roving lying around from my former life as a historical interpreter (spinning wool, amongst other activities), and never knew what to do with it. Now I’m going to hunt through my sweaters to see if any of them need mending!

  • Reply Heather Briggs October 24, 2019 at 11:33 am

    Fantastic timing. I was just about to take my damaged sweaters to the salvation army. Do you think this same method would work for socks? I hate getting rid of my lovely wool socks when the heels are worn.

    If anyone is interested in specific shapes ( I can do a heart, but that’s about it!),try using a cookie cutter as a template…the small “ canapé” cutters are perfect to use as a guide. Set them down , stuff in the roving, poke, and viola! You’ve got the perfect shape!! I’m going to Japan in a few weeks and plan on hitting one of the stores that have, literally, thousands of small “cookie” cutters they use for their veggies and such for the kiddos lunch boxes. A great thing to keep a lookout in yard/estate sales….

    Do you think this is possible on the fingertips of gloves? I came back to this post to gather supplies for my favorite gloves, but then realized I can’t really access the inside of the hole area.. 🙁

    • Reply ERIN BOYLE December 11, 2019 at 2:33 pm

      I think there are lots of possibilities here! I’d try stuffing an alternative brush or pad into the finger of the glove! Certainly a small “finger” of dense foam would work well and would be easiest, but if you don’t want to use foam, I can imagine a small cleaning brush or something similar working! Depending on the size, I’m not convinced that a toothbrush might not be perfect! Basically you want something in there so that you don’t end up felting the two sides of the finger together. It should be supple enough that your felting needle won’t bend when it hits it, but not so soft that you end up felting the stuffing! Good luck! I’m sure you’ll find a workaround!
